You will be in the store for at least 30 minutes. You should plan a point in your schedule when you can dedicate that amount of time.

As was stated in the previous post. This isn't Express where you pick out your shirt then pay.

If you don't want to wait in the store, call and have them send one to you and you can insert in your device at your leisure.

Everyone at the Verizon store has a specific job, just like at your job. Don't diminish any one person's function because you think it should be so. Imagine if there wasn't someone there keeping an order.
